Wear plates are very hard steel plates that can come in a variety of different thicknesses. These plates are typically welded in areas of machinery and equipment where there is already a significant amount of wear and tear. It’s important to understand that not every machine needs wear plates. However, the presence of wear and tear that’s caused by abrasion may signal that it’s time for you to start using them.
Wear plates are most commonly applied to machines that rotate or slide when they are being used. While wear plates are beneficial because they can help you maximize the life of your machinery, they are also advantageous because they are easy to install and relatively inexpensive when compared to the cost of replacing an entire part. The types of machinery that can be protected with wear plates are used across a wide range of industries, which makes them useful for practically any kind of business.
Different Types of Wear Plates
There are three primary types of wear plates that you should know about, which include ones that are made from minerals, ones that are made from ceramic liners, and low-friction UHMWPE options. Along with the three primary types of wear plates, each wear plate requires some base parts with softer materials that allow the plates to reach desired efficiency. Before you decide which of the three wear plates is right for you, it’s important that you understand the benefits of each.
Ceramic Liner Plates
Wear plates that are comprised of ceramic liners can lessen the amount of sliding abrasion that occurs while also limiting damage caused by moderate and heavy impacts. Because the surface of these liners is smooth, friction will be effectively reduced when the components within the machinery are sliding. These sliders are ideal for very specific uses.
The exact hardness of the base material that you choose for the plate determines what the coating will be. The right coating will allow the plate to function at peak capacity. Harder wear plates typically provide better wear resistance. There are many types of mineral coatings that you can select from when choosing a wear plate, which include:
Grade 50B steel
A variety of additional hard metals
Any of these coatings will serve you well if you would prefer to use a mineral plate for your machinery.
The UHMWPE in low-friction UHMWPE stands for ultra high molecular weight polyethylene, which is a material that is molded into rod and sheet shapes before being used as wear plates. Once the material has been molded into a rod or sheet, it will be bolted directly to the machinery. Despite the fact that these wear plates are highly effective, they are typically used for specific applications. Low-friction UHMWPE plates are commonly applied to gears, canning lines, conveyor flights, skid plates, and sprockets. The main benefits of using low-friction UHMWPE include:
Resistant to impact
Resistant to friction
Resistant to a wide range of chemical
Primary Applications for Wear Plates
The main types of machines and components that could benefit from wear plates include:
Equipment for moving heavy earth
Aluminum and steel mill equipment
While these are the primary machines that wear plates are used with, some additional applications for steel plates include:
Wear rings and segments
Punch press applications
Various mining tool
No matter the application you use a wear plate for, it should be able to extend the life of the machinery in question. When you’re selecting wear plates for your machinery, keep in mind that the hardness of the plate can make a significant difference in how the plate is being used. While harder and more durable plates will last longer, there are some parts that require a softer material that will wear out before the main surface does. As such, it’s important that you take the type of machine into account when assessing which wear plate you should use.
Wear plates are utilized by a wide variety of companies. If the equipment that your company uses is outfitted with components that come into contact with corrosive or abrasive materials, wear plates can be beneficial. Wear plates are commonly used within aluminum mills, steel mills, pipe mills, military facilities, mining facilities, and chemical companies.
These wear plates are designed to last for a very long time no matter which type of machine you pair them with.
While wear plates aren’t always essential, they can make it easier for you to maintain the quality of the high-end equipment and machinery that your business uses. Now that you know about the various types of wear plates, it should be easier to select ones that would work well in your business.
Ordering a wear plate from WALDUN
In some cases, we can modify your equipment to incorporate these liner plates when not in the original equipment design. If your equipment has lost some efficiency or does not hold the same tolerances as new, inspect the worn parts. There could be an easy and cost effective fix to the problem.
In fact, you can place it in the rankings of the best and the most abrasion and wear resistant steels in the market.
Composition of Abrasion Resistant Steel
Different types and kinds of Abrasion resistant steel have different compositions.
But, the most common and the most typical elements and compounds include:
But, these aren’t the only elements and compounds used in the manufacturing and the production of Abrasion resistant steel.
There are some manufacturers that experiment by using other materials and compounds for their abrasion and wear resistant plates.
Can You Cut Abrasion Resistant Steel?
Abrasion resistant steel resist abrasion, as well as other kinds of wear; but that doesn’t mean that you wouldn’t be able to cut it.
Cutting of abrasion resistant steel
You can achieve the act of cutting abrasion resistant steel if you use the correct materials and cutting procedures – laser cutting, among others.
Two-Body vs. Three-Body Abrasion
Little did we know that abrasion, one of the most common types of wear, can be categorized into two different categories: two (2) body and three (3) body.
Visual difference between 2 and 3-body abrasion
Two-body abrasion is the type of abrasion where surfaces slide off of each other; in which one of the surfaces dig and remove material off of the other.
Three-body abrasion, on the other hand, is the type of abrasion where material from both surfaces remove either from their own surfaces or from both.
If you use abrasion resistant steel, you can be safe from any of these types of abrasion.
Applications of Abrasion Resistant Steel Plate
We know abrasion resistant plates to be an excellent agent for resisting wear and abrasion – but where can you find it useful?

Which industries can utilize Abrasion resistant steel plates? Industries such as the following can find abrasion resistant steel beneficial for their processes:
Power Generation and Energy Industry
Construction and Structural Industry
Coal Mining Industry
You can also choose to use AR steel plates to lengthen the lifespan of your parts and components, renew, restore, or rehabilitate worn-out parts, and to clad parts of heavy-duty and industrial machinery.
AR steel plates are flexible and versatile – you can use them in a lot of different applications.
Is Abrasion Resistant Steel Impact Resistant?
Yes – but it will depend on the hardness level of a particular AR steel.
As we can remember, the higher the hardness level of AR steel, the more likely it is to break when it undergoes a certain degree of impact.
For instance, a steel plate might be hard, but it might not perform well under strong and heavy impact.
However, all AR steel grades are resistant to a particular impact degree.
Importance of Abrasion Resistant Steel in the Construction Industry
It’s a no-brainer to think that steel that is able to resist abrasion is an important element in the structural or the construction industry.

What is AR plates?
AR plates are designed to provide protection to the occasion or part that needs to be worn. AR plate makes your equipment last longer and reduces the maintenance downtime brought about by repairs. It can significantly reduce your costs.
Name: NM means wear resistance in Chinese languages, and the number followed represents the average Brinell hardness.
Heat treatment methods: high temperature tempering, quenching + tempering
What is AR plate standard?
In China, AR plate is named NM, like NM360, NM400, NM450 and etc.
Followed are the corresponding foreign standards for NM wear plates.
High welding performance wear-resistant steel plate: WNM360L.
How to cut AR plates?
In fact, cutting AR wear plates is same as cutting plain low carbon and low alloy steel. The key is to prevent cracks from appearing on the surface of the material. Since AR plates have a wear-resistant layer, their thickness and hardness must be higher than ordinary plates. Then the chance of cracks appearing when cutting will be higher as well.
When cutting AR wear plates, preheating should be done beforehand, and the preheating temperature is determined by the thickness and quality level of the wear plate. It is also possible to cut at low speed, but this is the method to be used when it is not possible to preheat the whole plate.
The correct use of the slow cooling method is also good for reducing cracks in the cutting of wear-resistant plate. For the newly cut wear-resistant plate with temperature, it should not be stacked, but should be covered with an insulating blanket to gradually reach the cooling requirement.
For the cutting of wear-resistant plate, there is a special measure, that is, immediately after cutting to take heating, that is, low-temperature tempering, can effectively eliminate the cutting residual stress, reduce the production of cracks.
Water jet cutting, applicable to AR wear plate cutting, and the effect is very good. Not only the heat-affected zone of the cutting is small, but also it can prevent the original properties of the workpiece from being affected, and the key is to get a good quality cut without distortion.
How to judge AR plate laser cutting quality?
AR plates’ laser cutting processing quality, generally refers to the cutting dimensions accuracy and the cutting edge quality.
Following four factors:
(1) The incision width and the surface roughness.
(2) The the heat-affected zone, and if have burns.
(3) The incision section corrugation.
(4) The incision cross-section or the lower surface hanging slag.
The main factors affecting the quality of laser cutting can be divided into two categories: one is the processing system performance and the influence of light; the other is the impact of processing material factors and process parameters.
What is AR plate chemical composition?
What is annealing process of AR plate?
If you want to produce high strength AR plate, you must apply to the successive annealing technology, that is, the cooling technology.
The most important point of successive annealing is that the speed of cooling in the cooling section should be appropriate and fast.
In fact, the temperature is also a very important element.
In order to prevent the steel coil layer bonding between, hood furnace temperature is limited, can’t be too high, generally not beyond 720 degrees.
What is advantages of AR400 wear plate?
AR400 wear plate has high strength and fracture resistance; high impact strength; excellent wear resistance.
AR400 wear plate through a special heat treatment process, the steel has both high strength and high resistance, and outstanding casting process-ability.
The wear resistance is more than 2 times better than high manganese steel and high chromium steel.
Its tensile strength is up to 1,950 MPA, elongation at break is 17%, section shortening rate is 38%, HRC55.
It has good mechanical processing function and casting function and welding function.
What is wear mechanism of wear-resistant plate?
The well-known wear mechanisms are adhesive wear, corrosion wear, fatigue wear, erosion wear, micro-dynamic wear, impact wear and etc.
How to indicate the wear resistance of wear plates?
Abrasion resistance is the ability of a material surface to resist wear. It is expressed in terms of wear rate, which is equal to the quotient of the difference in mass of the specimen before and after wear under standard test conditions and the surface area of the specimen subjected to wear.
The greater the wear rate, the worse the wear resistance.
What is Mn16 wear plate?
Mn16 refers to the content of element Mn in about 1.6. 16Mn is called low alloy high strength structural steel, 16Mn is the old Chinese standard grade, the current Chinese grade is called Q345. And Mn16 belongs to high manganese steel, is a widely used wear-resistant steel, wear-resistant and impact resistant.
Clad wear-resistant steel vs AR500 wear-resistant steel
Cladding wear plates are more wear resistant because the cladding plate is made of an alloy to improve wear resistance.
AR500 mainly relies on tempering to guarantee wear resistance.
However, the price of clad wear steel is higher.
AR Wear Steel VS HARDOX Wear Plate
Wear-resistant steel plates can be divided into Chinese wear-resistant steel plate and imported Swedish wear-resistant steel plate. These two kinds of wear-resistant steel plates, each have its own performance characteristics.
